Flood Watch
In short
A flood watch is in effect across the Hawaiian Islands through Wednesday night, 29 October 2026, as remnants of Olana bring intense downpours to the state.
What is happening
Heavy rain is moving across Maui County and the Big Island following significant soaking on Oahu. In West Texas, a flood watch has also been issued for the Midland and Odessa regions due to expected rainfall.
When
In Hawaii, the watch lasts through Wednesday night; in West Texas, the watch is scheduled from Thursday morning through Friday afternoon.
Why it matters
These weather patterns increase the risk of flash flooding and dangerous driving conditions. Emergency services must monitor rainfall totals to decide when to escalate alerts to the general public.
Easy to mix up
A flood watch is often confused with a flood warning; a watch means flooding is possible, while a warning means flooding is imminent or already occurring.
